Chithunzi cha ASTM A213 T12(ASME SA213 T12) ndi chitoliro chochepa chachitsulo chopanda aloyi chopangidwira ntchito yotentha kwambiri.
Zomwe zimapangidwira kwambiri ndi 0.80-1.25% chromium ndi 0.44-0.65% molybdenum, zomwe zimayika ngati chitsulo cha chromium-molybdenum alloy. Amagwiritsidwa ntchito kwambiri m'malo otentha kwambiri komanso opanikizika kwambiri monga ma boilers, ma superheaters, ndi osinthanitsa kutentha.
T12 chitoliro ali osachepera makonde mphamvu 415 MPa ndi osachepera zokolola mphamvu 220 MPa.
Dzina la UNS la girediyi ndi K11562.
Botop Steel ndi katswiri wodalirika komanso wodalirika wazitsulo zazitsulo zazitsulo komanso wogulitsa ku China, wokhoza kupereka mapulojekiti anu ndi magulu osiyanasiyana a mapaipi azitsulo, kuphatikizapoT5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590),ndiT91 (K90901).
Zogulitsa zathu ndi zamtundu wodalirika, zamtengo wapatali, ndipo zimathandizira kuwunika kwa anthu ena.
Kuti mudziwe zambiri, chonde titumizireni lero!
Wopanga ndi Mkhalidwe
Mapaipi achitsulo a ASTM A213 T12 adzapangidwa ndi njira yopanda msoko ndipo azikhala otentha kapena ozizira kumaliza, monga tafotokozera.
Kutentha Chithandizo
Mapaipi onse achitsulo a T12 adzalandira chithandizo cha kutentha.
Njira zovomerezeka zochizira kutentha zikuphatikiza full kapena isothermal annealing, normalizing ndi kutentha, kapenasubcritical annealing.

Chubu chilichonse chidzayesedwa popanda kuwonongeka kwa magetsi kapena kuyesa kwa hydrostatic.Mtundu wa mayeso oti ugwiritsidwe ntchito ukhala pakusankha kwa wopanga, pokhapokha atanenedwa mwanjira ina yogulira.
Njira zoyeserazi zizichitika molingana ndi zofunikira za Gawo 25 ndi 26 la ASTM A1016.
Kukula kwa machubu a ASTM A213 T12 ndi makulidwe a khoma nthawi zambiri amakhala ndi mainchesi amkati kuyambira 3.2 mm mpaka ma diameter akunja a 127 mm, ndi makulidwe ochepa a khoma kuchokera ku 0.4 mm mpaka 12.7 mm.
Kukula kwina kwa mapaipi achitsulo a T12 atha kuperekedwanso, malinga ngati zofunikira zina zonse za ASTM A213 zikukwaniritsidwa.
ASTM A213 T12 alloy zitsulo machubu opanda msokonezo amagwiritsidwa ntchito makamaka m'malo otentha kwambiri komanso opanikizika kwambiri. Zomwe zimagwiritsidwa ntchito zikuphatikizapo
1. Zotenthetsera ndi Zotenthetsera
Amagwiritsidwa ntchito m'mafakitale amagetsi opangira ma superheater ndi machubu otenthetsera omwe amagwira ntchito pansi pa kutentha ndi kupsinjika.
Amagwiritsidwa ntchito kwambiri ngati machubu opopera magetsi m'malo opangira magetsi, malo obwezeretsa zinyalala, ndi ma boiler a mafakitale.
3. Kutentha Kutentha
Oyenera kutentha machubu m'mafakitale a petrochemical ndi mankhwala chifukwa cha kukana kwake bwino komanso kukhazikika kwamafuta.
4. Ng'anjo ndi Machubu Otentha
Amayikidwa mu ng'anjo ya ng'anjo, machubu otenthetsera, ndi zotenthetsera zomwe zimafunikira kukana makutidwe ndi okosijeni komanso kulimba kwanthawi yayitali.
5. Kupopera Kwapaipi mu Mphamvu ndi Zomera za Petrochemical
